JOSEPH V. TIBBETS, OF NEW YORK, N. Y.

HOT-AIR REGISTER.

Specification of Letters Patent No.

To all whom it may concern Be it known that I, JOSEPH V. TIBBETS, of thecity, county, and State of New York, have invented certain new anduseful Improvements in the Arrangement and Construction of Hot-AirRegisters for Side lValls of Apartments; and I do hereby declare thefollowing to be a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, in which- Figure 1 is a verticalsection; Fig. 2, a front view.

It may be proper to remark that there are two classes of apparatus forregulating the flow of heated air from a hot air furnace into a room theone located in the floor the other in the side-wall and although floorregisters have simetimes been used for the wall they are so defectivefor such purpose as to be objectionable. Again the usage now is in themost perfect arranged furnaces to carry up pipes separately for eachstory, thus if three floors are to be heated three pipes start from thefurnace one of which terminates at the first floor above a second at thenext and the third extends to the upper story. It will be seen that thisinvolves a considerable expenditure in the multiplication of pipes, andsingle pipes,

with openings into each story, are often used. When but one pipe is madeto convey the heat from the furnace if the top register is open it isvery apt to draw all the heat up past the two lower registers so thatthe lower part of the house fails to get heated and it becomes necessaryto shut the heat 0E above in order to heat below. To prevent thesedifficulties and expenses is the purpose of my new device which giveswith a single hot air flue perfect command of the heat on the firstfloor.

The construction is as follows: a, a, is the ascending pipe or hot airfiue from the furnace (which is built into the wall) 6 is the opening ofthe register into the room behind this opening I hinge, in the center ofthe ascending pipe, two wings (Z, c, at the point e which is the axis onwhich they pivot; these two wings or valves it will be noticed mayassume the position shown in the draw- 18,026, dated August 18, 1857.

ing in which case they shut off all the heat from the rooms above anddischarge all the heated air into the first room through openings 1) ifthe two wings are placed vertical as seen by the blue lines then thecurrent takes its natural course if they are in position the reverse ofthe one in which they are placed in the drawing, (as indicated by thered lines) all the heat is shut off above and below; if c is in itspresent position and (I brought into the place of the red line all theheat passes by the first opening I) if it is set in the position of theblue line 0 being as before, half the heat goes to the lower room if (Zis in its present position and 0 is thrown back to the red line thecurrent is deflected toward opening 6 and thus tends to throw a portioninto the lower room. It is obvious that other intermediate positionswill vary the extreme results above indicated which may be varied to anydegree so as to render the effect of a single hot air flue as perfect asa series of separate flues for each story.

My device for moving and holding the valves 0, (Z, are two straight armsf one near each side of opening I) these project beyond the face of theregister sufficiently to handle they are afiixed to the valve at thepivot and pass through a curved collar h concentric with the turningpoint, a spiral spring wound around and attached to the arm makespressure and friction upon the collar h which is attached to the sideand thus the valves are retained at any point at which they are set ascrew 71 on the arm f firmly fixes it in place when desired.

Having thus fully described my improved regulating register I wish to beunderstood as not claiming a register with a valve for turning the heatas such has been before essayed but What I do claim is The valves 0, d,placed in the ascending pipe at or near the center with independentmovements as, and for the purposes, set

forth.
